Ginseng radix (GR) is often used in traditional Japanese kampo medicine. We studied the effect of GR on glucose and maltose transport in rat and human duodenal mucosa by Ussing's method, and on smooth muscle movement in rat duodenal muscle by Magnus' method. GR inhibited absorption of glucose or maltose in rat and human duodenal mucosa, but increased duodenal muscle movement. It suggests that the inhibition of sugar absorption by GR is more dominant than enhancement of duodenal muscle movement by GR.
The colonic wet weight was similar among the four groups while the macroscopic damage score, histological score, mucosal myeloperoxidase activity and the mucosal LTB4 level were significantly decreased in the TNB-A and TNB-H groups. Argatroban, as well as heparin may be effective for treatment of TNB-induced colitis.
Although only the first 24 hours of mucosal injury were observed in the present study, the most likely mechanisms by which monochloramine caused injury to the gastric mucosa appeared to be both oxidative damage and a reduction in blood flow, impairing the mucosal defense mechanism.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
